Perhaps you should try some spelling variations:
de communication » mobile communication, online communication
your development » youth development, source development, power development
development en » developpement en, development menu, development eco
des variation » does variation, de variation, der variation
typology des » typologie des, typologie der, typology _
des sous » des sols, de sous, des soins
des soa » das soa, des sols

You may be able to get more results by adjusting your search query.

• The words AND, OR and NOT may confuse the search; try adding quotes: "typology des variation ((des soa) OR (des sous)) de communication _ your development en afrique.~".
• Adding a wildcard symbol may retrieve word variants: typology des variation ((des soa) OR (des sous)) de communication _ your development en afrique.*.
